In a fictional prehistoric era, creatures are part dinosaur and part machine, from Craneosaurus and Garbageadon to the powerful Tyrannosaurus Trux. Giant Ty Rux, a half-dinosaur, half-construction truck, teams up with his small buddy Revvit and their crew as they face the trouble caused by the evil D-Structs. Together, these unusual friends navigate a world built on big machines, bigger creatures and constant challenges.
